PGT Construction in Los Altos, CA | Gold Star Contractors
We’re Gold Star Contractors, and we provide independent PGT construction service across Los Altos, CA. We install, repair, re-glaze, and replace PGT WinGuard and PGT Aluminum/Vinyl Series windows and doors on the ranch homes and custom rebuilds this city is known for. What sets our Los Altos PGT work apart is simple: we build every schedule around the city’s own per-trade plan-check process, so your window or addition timeline reflects how Los Altos actually reviews work, not how a county office might. Call (833) 382-8544 for a free estimate.
Why Los Altos Residents Choose Us for PGT Service
We’ve spent years pulling, re-flashing, and re-glazing PGT aluminum and vinyl units across Los Altos as a Los Altos General Contractor, so we understand how these window and door systems actually fail under winter rain and foothill sun. That local experience matters because PGT frames respond differently to Los Altos conditions than they do in coastal towns. The flat, low-pitch ranch roofs that dominate the 1940s through 1960s housing stock here collect water differently, and that shows up in head flashing and sill rot on original units.
We’re an independent contractor. Not authorized, sponsored, or endorsed by PGT. That independence means we quote repair versus replacement honestly. When a PGT frame is sound and only the glazing or hardware is tired, we repair it. When the frame is pitted, racked, or the rough opening behind it is rotted, we tell you straight that replacement is the better spend. No factory line, no upsell. Noel Carranza, our owner, came up doing concrete and finish carpentry before building this company, and he still treats every window opening like a small framing job: get the flashing right, and everything else holds.
We’re also a full-scope general contractor. So when a PGT window replacement in Los Altos turns into a rough opening rebuild, a shear wall correction, or a re-flashed addition wall, we handle all of it with one project team. One call, done right, that’s the only way Noel knows how to run a job.

Common PGT Construction Problems We Solve in Los Altos
- Head and sill flashing failures on original PGT aluminum sliders. On the flat, low-pitch ranch elevations common across Los Altos, original installs often had minimal flashing detail. Winter rain drives water into the rough opening, and the framing rots behind the frame before anyone sees it on the interior. We open the wall, rebuild the rough opening, and reset the unit with proper pan flashing and a sealed sill.
- Pitted and chalked PGT aluminum frames on 1980s and 1990s installs. South- and west-facing rear elevations in Los Altos take hard afternoon sun, especially where mature oaks no longer shade the glass. The anodized or painted finish on PGT aluminum breaks down before the glazing does. We re-finish where the substrate is intact and replace where corrosion has compromised the frame.
- Stiff or seized rollers, weatherstripping, and corner gaskets on PGT sliding glass doors. This is one of the most common calls we get on ranch homes in Los Altos that were never re-glazed. Doors drag, air leaks, and water tracks past the threshold. We stock PGT-compatible OEM-spec rollers and gaskets locally for fast turnaround, and we re-square the door as part of the repair.
- Original PGT units set with no pan flashing, sealed only with caulk at the stucco. During Los Altos tear-down-and-rebuild remodels, we routinely find this. Those units must be pulled, re-flashed, and reset before the new two-story home goes up around them. Skipping this step guarantees a leak in the first winter.
- Unpermitted additions with non-compliant PGT window openings. Los Altos has a long history of unpermitted additions and partial slab foundations. When we open up a wall for a remodel, we often find PGT units that don’t meet current egress or structural opening requirements. We bring the opening up to code before anything else moves forward.
PGT Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos pulls permits and plan-checks through its own building division rather than the county, and window and door changes on a remodel or addition are reviewed trade-by-trade with a neighbor-notice period. That means a PGT opening change can sit in city plan-check longer than the install itself takes. Anyone who tells you a Los Altos PGT window replacement is a two-day job hasn’t accounted for the city’s review queue. We build that Los Altos-specific review time into every window and addition schedule from the first site visit. It’s not a delay; it’s how this city manages neighbor-sensitive design, and we’d rather set expectations correctly than promise a timeline that collapses at plan check.
On a Country Club-area ranch off University Avenue near PGT service in Stanford, we opened up a rear wall during a kitchen-and-addition remodel and found the original PGT aluminum sliders set with no pan flashing. Winter rain had rotted the sill plates. We rebuilt the rough openings, re-flashed and re-shimmed them, and reset PGT WinGuard units with proper pan flashing and a sealed sill. The door now closes square and the wall behind it stays dry through the rainy season. That’s the difference between looking at a window and knowing the wall behind it.
PGT Models & Products We Service in Los Altos
We work on PGT WinGuard Aluminum impact-resistant single-hung and sliding glass door units, WinGuard Vinyl single-hung and sliding windows, Aluminum Series fixed and awning windows commonly specified on custom rebuilds, and Vinyl Series casement and picture windows.

FAQs – PGT Construction in Los Altos
Yes. Los Altos reviews window and door changes through its own building division, not the county, and the process includes per-trade plan check and a neighbor-notice period. A straightforward PGT replacement may take a few weeks in plan check depending on current backlog. We handle the permit application and build the review time into your schedule. Call (833) 382-8544 for a timeline specific to your street.
If the frame is square and the rough opening behind it is dry, we can typically repair the sill flashing, replace the weatherstripping and rollers, and re-seal the unit. If we find rotted sill plates or a racked frame, replacement is the better spend. We’ll open a small area of the wall to check before quoting. Call (833) 382-8544 to schedule an inspection.
Yes, in many cases. If the aluminum or vinyl frame is sound and only the insulated glass unit or hardware is tired, we re-glaze in place and replace rollers, gaskets, and weatherstripping with PGT-compatible OEM-spec parts. This is usually the most cost-effective path on ranch homes where the original PGT frames are still structurally fine, including those we’ve serviced with our Loyola PGT service. We’ll tell you if the frame won’t support re-glazing.
On foothill-side edges of Los Altos, yes. The wildland-urban-interface fire concern has pushed Chapter 7A exterior ignition-resistant requirements onto certain new and remodeled structures. That can mean tempered or multi-pane glazing, specific frame materials, and non-combustible exterior detailing. We review your lot’s specific zone and spec PGT units accordingly.
We do, and we pay close attention to the head flashing. Flat and low-pitch roofs don’t shed water as quickly as steeper pitches, so PGT units on ranch homes here take more direct water at the head. When we replace windows on these elevations, we re-flash the head and sill to handle the actual water load, not just the factory minimum. Call (833) 382-8544 for an exact quote – estimates are free.
